creates a proof of lock change which is an array of votes that proves the validator was permitted to change locked block and vote again. This proof is stored in the evidence pool and is used as a part of amnesia evidence
Predominantly following the discussions regarding the conventions of using mocks, I have decided to revert back to the previous state where mocks were specialized and stored in the separate packages that used them rather then have a generalized mock in the evidence package.
This also was a problem as the state package were running tests too slow and occasionally timing out unnecessarily.
For the replay file I renamed mockEvidencePool to emptyEvidencePool to illustrate that it was intentionally like this and not give the impression that testing software was being used in production
Closes: #4786
to prevent data races
note: when we check the ConflictingHeadersEvidence, the copy is used.
Closes#4749
Also, iterate over valToLastHeight instead of loading validators. While it might be slower than accessing a single key in goleveldb, the new code is better adapted to ConsensusParams changes.
to prevent malicious nodes from sending us large messages (~21MB, which
is the default `RecvMessageCapacity`)
This allows us to remove unnecessary `maxMsgSize` check in `decodeMsg`. Since each channel has a msg capacity set to `maxMsgSize`, there's no need to check it again in `decodeMsg`.
Closes#1503
merged the existing store into pool, consolidated the three buckets into two, used block height as a marked for committed evidence, evidence list recovers on start up, improved error handling
Closes: #4530
This PR contains logic for both submitting an evidence by the light client (lite2 package) and receiving it on the Tendermint side (/broadcast_evidence RPC and/or EvidenceReactor#Receive). Upon receiving the ConflictingHeadersEvidence (introduced by this PR), the Tendermint validates it, then breaks it down into smaller pieces (DuplicateVoteEvidence, LunaticValidatorEvidence, PhantomValidatorEvidence, PotentialAmnesiaEvidence). Afterwards, each piece of evidence is verified against the state of the full node and added to the pool, from which it's reaped upon block creation.
* rpc/client: do not pass height param if height ptr is nil
* rpc/core: validate incoming evidence!
* only accept ConflictingHeadersEvidence if one
of the headers is committed from this full node's perspective
This simplifies the code. Plus, if there are multiple forks, we'll
likely to receive multiple ConflictingHeadersEvidence anyway.
* swap CommitSig with Vote in LunaticValidatorEvidence
Vote is needed to validate signature
* no need to embed client
http is a provider and should not be used as a client
Add Has function, create better handling of errors when adding evidence, usage of error types.

* panic if peer has no state
https://github.com/tendermint/tendermint/issues/2721#issuecomment-435347165
It's confusing that sometimes we check if peer has a state, but most of
the times we expect it to be there
1. add79700b5/mempool/reactor.go (L138)
2. add79700b5/rpc/core/consensus.go (L196) (edited)
I will change everything to always assume peer has a state and panic
otherwise
that should help identify issues earlier
* abci/localclient: extend lock on app callback
App callback should be protected by lock as well (note this was already
done for InitChainAsync, why not for others???). Otherwise, when we
execute the block, tx might come in and call the callback in the same
time we're updating it in execBlockOnProxyApp => DATA RACE
Fixes#2721
